Answer 1

Explanation:

Biogas is a mixture of gases produced by the breakdown of organic matter in the absence of oxygen. It mainly consists of carbon dioxide and methane. Biogas can be produced from raw materials like agricultural waste, manure, plant material, etc. It is a renewable source of energy and also known as "Gobar Gas".

Working of Biogas plant:-

1. Biogas is made in a digester which is a tank filled with bacteria that eat organic waste and give flammable gas, i.e, Biogas.

2. The bacteria in the plant should be taken care and also well and proper food to be given.

3. The bacteria convert organic matter into methane gas through anaerobic respiration.

4. The operator of the biogas system feeds the digester with household by-products like kitchen waste, manure, etc

5. The methane gas produced can be used for cooking, lighting, etc.

6. The waste which is fully digested will produce an organic fertilizer.

7. This is also called anaerobic digester, biodigester, or a bioreactor.
